I think I'm figuring out the problem: wherever I've ended up in a medium-to-large department (in my country or elsewhere) it has turned out that the people there are already lined up for the nice things, and they aren't really willing to share. I'm expected to play the role of a workhorse, period, with nothing that I'd regard as special for me to do. Only... I'm single and have no real expenses or reason to stay in one place, and there are not that many people around able to do even the normal "workhorse" stuff that I do, so there is no paucity of work as long as I'm willing to move.
The way I see things these guys will probably fall short of their promises just like the previous ones did (probably in a more polite way though), and while I'm not bad off right now, I'm not specially happy either. Odds are that sometime next year I'll go elsewhere (it may happen sooner if they do something that annoys me, later if they throw a bone my way).
I think the funny thing is that I tend to be very frank about what I do and what I expect, but apparently people think I'm full of shit and that I'll basically settle for whatever they decide to give me in the end (I have my own theories as to why, which spin around how they usually treat people and how it works out). As it turns out they're wrong. I'm single, I have no significant expenses, and I can afford both to move around and to stay unemployed if nothing convinces me.
Right now I'm not uncomfortable, because I have good work hours, good weather and tbh my current activity is rather simplistic compared to what I'm used to. But I'm not doing what I came to do and I'm pretty f*ing far away from home As soon as something more interesting pops up back home, or the HSE hiring freeze ends, or they simply annoy me beyond my tolerance threshold, I'm hitting the road
